unification of the various types of soil recognition and it's utility red and black clay sand and alluvial soil also
Answers
Answer:
The soil is one of the most important natural resources that nature has provided to humankind. It actually sustains life on the planet as it is an essential ingredient for growing plants. But have you noticed that not all soils look the same? This is because the soil has a large range of variety. In fact, there are thousands upon thousands of soil types in the world.
There are a variety of reasons for these variations in soil. Primarily soils are different from region to region due to the climatic conditions (like temperature, rainfall etc). The variety of flora and fauna of a region also has an influence on the soil profile. And there can even be a human influence.

And there can even be a human influenceOne of the main regions to study the various types of soil in India is to understand how it affects the biodiversity of a region. let us take a look at some of the major types of soil we find in India.
Alluvial Soil
Alluvial SoilThese are fertile soil deposited by rivers on and near their banks. These soils are majorly found in the northern plains of the country. The most fertile alluvial soil is found in the Ganga valley, where it is deposited by river Ganges. These soils cover almost 35-40% of the region of India
Black Soil
Black SoilBlack Soil are characterized by their deep black colour. Their composition has a large amount of clay. This helps the black soil retain water, making them ideal for crops that require water year round. This also gives them a unique self-ploughing ability.
Red Soil and Yellow Soil
Red Soil and Yellow SoilThese distinct soils are named after their hues. Red soil gets its colour from the iron found in its composition in a crystallized form. The soil takes on a yellow colour when it is hydrated. These soils are generally found in the Western Ghats, Odisha and Chattisgarh.
Laterite Soil
Laterite SoilSuch soils are found in regions of high temperature and very high rainfall. The rains will wash all the nutrients from the soil, leaving it infertile. The leaching process will leave behind iron-rich soil, absent of silicon. The humus composition is also affected by bacteria and fungi that thrive in high temperatures.
